Strategy and Performance Evaluation of Low-Frequency Variant Calling for SARS-CoV-2 Using Targeted Deep Illumina Sequencing
quasispecies in diagnostic samples. The performance of detection and quantification of low-frequency variants using whole genome sequencing (WGS) of SARS-CoV-2 remains largely unknown. Here, we evaluated the ...
Regulation of Neurotoxin Expression by Culture Conditions.
pH levels (pH 7.8), which was confirmed by the quantification data obtained with the recently validated targeted LC- MS / MS approach. CONCLUSIONS: Non-standard culture conditions lead to different ...
In Vivo Kinetics and Biotransformation of Aflatoxin B1 in Dairy Cows Based on the Establishment of a Reliable UHPLC-MS/MS MethodDataSheet1.docx
developed and successfully validated by the determination of linearity (R2 ≥ 0.990), sensitivity (lower limit of quantification, 0.1–0.2 ng ml−1), recovery (79.5–111.2%), and precision relative standard ...
Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.
be respected (< 20mg/ml). The main objective of this paper is to develop a handheld NIR, Raman or SERS spectroscopic method combined with chemometrics (PLS and PCA) for detection and quantification ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
requirements of ICH guidelines for the quantification of four flavourings with a potential health concern for e-cigarette users. Health Topics: E-cigarette E-cigarette E-sigaret Service: Médicaments et ...

CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
method for the routine analysis of CBD oil samples. Eighteen CBD samples were selected on the Belgium market for analysis. This method allows the quantification of CBD, the legality check for the Δ9- THC ...
Evaluation of the shucking of certain species of scallops contaminated with domoic acid with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation
quantification (LOQ) and only these data were used for the assessment. Shucking in most cases resulted in a strong decrease in the toxin levels. Statistical analysis of the data showed that levels in whole ...
Mineral oil risk assessment: Knowledge gaps and roadmap. Outcome of a multi-stakeholders workshop
from one-dimensional chromatographic methods. This is required to enable adequate substance identification and quantification for input into risk assessment. A major gap in the exposure estimation is the ...
Evaluation of the shucking of certain species of scallops contaminated with lipophilic toxins with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation
edible and non-edible parts from contamination incidents. The majority of the concentration levels were below limit of quantification (LOQ)/limit of detection (LOD), especially in adductor muscle but also ...
